macos-sierra-shared: Backport change for consistency with other channels

While 17.03 does not have binutils-wrapper and thus doesn't need this to work, I'll be continuing to improve this on all 3 platforms for the immediate future. It's thus prudent to keep them somewhat in sync for sake of future cherry-picking. This post-dates the initial release of 17.03 and isn't used by anything there at the moment, so I deem churn like this inconsequential and thus acceptable. (adapted from commit eb326c9)
